is 0.9999999 = 1 true?

[caffeine$]

x = 0.999999
10x = 9.9999999
10x-x = 9.9999999 - 0.99999999
9x = 9
x = 1
0.9999999 = 1
so it should be true right?

 

[75hzAmine]

yess its true

 

[bruh gg]

ima not rly good in math but that may be right

 

[mysteryswitch]

no it is not obviously

 

[caffeine$]

no it is not obviously

but why not? i've just proven it

Limitation in notation of decimal numbers created the illusion that the two numbers are equal and an academic desire to keep everything neat and tidy lead to confirmation bias and the statement that, at some limit, the actual difference was essentially akin to 0.

so if the difference is 0, then they're the same right?

 

[vocanol]

help me to

 

[tsaglashgui]

YES its true

 

[mysteryswitch]

0.99999 is not equal to 1 due to the way floating-point numbers are represented in computers. Computers store numbers in binary, not decimal, and certain decimal values cannot be exactly represented in binary. As a result, some decimals may have a small amount of rounding error, leading to small inaccuracies in calculations.

PPL just simplyfied the calculation.

 

[MuhammadIshaq]

x = 0.999999
10x = 9.9999999
10x-x = 9.9999999 - 0.99999999
9x = 9
x = 1
0.9999999 = 1
so it should be true right?

yea it i s dude its common sense

 

[caffeine$]

yea it i s dude its common sense

well i wouldn't say it's common sense cause many people disagree with me

 

[aumjirnw]

true

 

[BullyMaguire]

as far as I know . true

 

[caffeine$]

as far as I know . true

have you tried calculating it yourself?

 

[riprip010533]

I think this part is wrong
10x-x = 9.9999999 - 0.99999999
9x = 9

 

[Cicuta914]

no, the measurements must be exact, 0.999999 is 0.999999 not 1

 

[caffeine$]

no, the measurements must be exact, 0.999999 is 0.999999 not 1

but i've just proven otherwise

 

[BullyMaguire]

yes i did
